Description
FIELD OF INVENTION

The present invention relates to a toolkit that includes a chain tool for removing a pin from a link of a chain.

BACKGROUND OF INVENTION

Referring to FIG. 7, a conventional toolkit includes a frame 110 with two lateral members 111 and two bolts 121 extending between the lateral members 111. A tool set 120 is pivotally connected with each of the bolts 121. A chain tool includes a holder 123 hung on one of the bolts 121 and a screw 124 installed on the holder 123. The toolkit includes a crowbar 130 and an Allen key 132 extending from the crowbar 130. In use, a link of a chain is held on the holder 123. The Allen key 132 is fit in a recess defined in the screw 124. The crowbar 130 is rotated in order to rotate and move the screw 124 on the holder 123. Thus, a pin is pushed from the link of the chain so that the link can be removed from the chain. Drawbacks have been encountered in using this conventional toolkit. Firstly, the chain tool cannot support the frame 110. Secondly, the chain tool occupies some space on the bolts 121 that would otherwise encompass one or more tools. Thirdly, the chain tool cannot be taken from the frame 110 in order to reduce the total weight of this conventional toolkit if the chain tool is not to be needed.

The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF INVENTION

According to the present invention, a toolkit includes a frame, at least one tool set and a chain tool. The tool set is pivotally connected with the frame. The chain tool is attached to the frame in a detachable manner. The chain tool is located in the frame in order to support the frame. The primary advantage of the toolkit of the present invention is the support for the frame by the chain tool.

Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description referring to the drawings.

BRIEF DESCRIPTION OF DRAWINGS

The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings.

FIG. 1 is a perspective view of a toolkit with a chain tool for removing a pin from a link of a chain according to the preferred embodiment of the present invention.

FIG. 2 is an exploded view of the toolkit shown in FIG. 1.

FIG. 3 is a cross-sectional view of the toolkit taken along line 33 shown in FIG. 1.

FIG. 4 is similar to FIG. 3 but shows the toolkit in another position.

FIG. 5 is similar to FIG. 1 but shows the toolkit in another position.

FIG. 6 is similar to FIG. 4 but shows the toolkit in another position.

FIG. 7 is a perspective view of a conventional toolkit that includes a chain tool for removing a pin from a link of a chain.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIG. 1, a toolkit 10 includes a frame 20, a first tool set 30, a second tool set 40 and a chain tool according to the preferred embodiment of the present invention.

Referring to FIG. 2, the frame 20 includes a first side or lateral member 21, a second side or lateral member 22, two bolts 23 extending between the first lateral member 21 and the second lateral member 22 and two nuts 24 engaged with the bolts 23. The first lateral member 21 includes two apertures 25 each defined in an end thereof and a recess 26 defined in a side thereof. The second lateral member 22 includes two apertures 27 each defined in an end thereof, two recesses 28 each communicated with related one of the apertures 27 and an aperture 29 defined in a center thereof. Each of the nuts 24 is fit in related one of the recesses 28 in a non-rotational manner. Each of the bolts 23 is inserted through related one of the apertures 25 and related one of the apertures 27.

The first tool set 30 includes a plurality of tools 31 each including a looped end in which one of the bolts 23 is inserted. Thus, the tools 31 are pivotally connected with the frame 20.

The second tool set 40 includes a plurality of Allen keys 41 each including a looped end in which the other of the bolts 23 is inserted. Thus, the Allen keys 41 are pivotally connected with the frame 20.

The chain tool includes a holder 50 and a screw 53. The holder 50 includes a block 51 formed thereon, a screw hole 52 defined therein, a handle 54 formed thereon and an Allen key 55 pivotally connected with the handle 54. A knob 56 is secured to the screw 53 so that the knob 56 can be operated in order to rotate the screw 53. A recess 57 is defined in the knob 56.

Referring to FIG. 3, the block 51 is put in the recess 26. The screw 53 is driven in the screw hole 52 through the aperture 29. The chain tool keeps the first lateral member 21 from the second lateral member 22. When held tightly, the frame 20 is not deformed because of the chain tool that keeps the first lateral member 21 from the second lateral member 22.

Referring to FIG. 4, the screw 53 is removed from the screw hole 52. At this instant, the holder 50 can be easily removed from the frame 20.

Referring to FIG. 5, a link of a chain 60 is held on the holder 50. The knob 56 is twisted in order to rotate and move the screw 53 on the holder 50. One of the Allen keys 41 is inserted in the recess 57. This Allen key 41 can be twisted in order to further rotate and move the screw 53 on the holder 50. Thus, a pin is pushed from the link of the chain 60. Hence, the link can be removed from the chain 60.

Referring to FIG. 6, after the toolkit 10 is used for some time, the bolts 23 tend to slack on the nuts 24. In this case, the Allen key 55 can be pivoted from the handle 54 and used to drive the bolts 23.

The toolkit 10 of the present invention possesses several advantages over the conventional toolkit discussed in Related Prior Art. Firstly, the chain tool supports the frame 20. Secondly, more tools can be attached to the bolts 23 since the chain tool is sandwiched between the first tool set 30 and the second tool set 40 instead of attached to the bolts 23 (FIG. 1). Thirdly, the chain tool can be taken from the frame 20 in order to reduce the total weight of the toolkit 10 if the chain tool is not to be needed.

The present invention has been described via detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
